Abstract: PURPOSE:To enable down cut and up cut work of a rotary plowing device, by a method wherein in a title device where a running system speed change gear is positioned above a main shaft and a PTO system speed change gear therebelow, a reversing device capable of making and breaking is situated on the outlet side of the PTO system speed change gear. CONSTITUTION:When a shifter 25 is controlled in a direction L, a shifter 31 is also driven, a gearing part 22A is coupled to a coupling ring 24 through the shifter 25, a PTO shaft 19 is rotated at a low speed, and the shifter 31 is brought into an OFF-state. When the shifters 25 and 31 are both controlled in the direction L, the shifter 25 is brought into an OFF-state, and the shifter 31 couples a gearing part 27A with a coupling ring 30 to bring a reversing device 26 into an ON-state. Inversely, when the shifter 25 is controlled in a direction H, coupling of a gearing part 23A to the coupling ring 24 causes high rotation of the PTO shaft 19, and the shifter 31 keeps the reversing device 26 at an OFF-state. This constitution enables execution of down cut and up cut work by means of a rotary plowing device.

IPC: H01L21/28
Filed: 1989-12-20
Abstract: PURPOSE:To prevent projection of an Si single crystal in a through hole by forming the hole in an insulating film on an Si substrate, then preheating the substrate at a specific temperature in a reduced hydrogen atmosphere, thereafter using source gas as disilane gas, and performing chemical vapor growth of an Si film on the substrate and the insulating film in the hole at a specific temperature.

Title: Braking force controller
Inventor: MATSUMOTO SHINJI
IPC: B60T8/1761
Filed: 1991-12-13
Abstract: PURPOSE:To improve controllability by preventing deceleration from being decreased as much as possible by a braking force control system which generates a difference in right and left braking force. CONSTITUTION:With a yaw rate F/B method, a controller determines a target different pressure DELTAP(S) which is generated in right and left wheels according to a yaw rate difference value DELTA(d/dt)phi, and target wheel cylinder (W/C) pressure at the right and left wheels is obtained so as to obtain a difference by increasing pressure at one wheel and decreasing pressure at the other wheel (S112-115). The target W/C pressure value is corrected according to the yaw rate difference value (S116), and brake fluid pressure is controlled by the value after the correction (S120). When the yaw rate difference value is large, correction is made larger at the decreasing pressure side to generate DELTAP(S). At the time of braking rotation by increasing or decreasing pressure which is efficient for preventing deceleration from being decreased, yaw rate control ability becomes better, for example, when the pressure decelerating side is made slightly larger than when increased pressure in a rotating inner wheel 1/2 DELTAP(S) is the same as decreased pressure in a rotating outer wheel 1/2DELTAP(S).
